|Highland Tank provides you with the strongest and most reliable grease interceptors in the industry - the best alternative to a grease trap. Highland interceptors are designed to remove animal and vegetable-based fats, oil, and grease (FOG) from wastewater discharged from food service establishments (FSE) primarily engaged in preparing or serving food to the public. Most municipalities have strict sewer discharge limits that govern the amount of FOG and solids that can be discharged by a FSE. The information available here will help you determine the right system for your specific site requirements. PDI/IAPMO approved models available, if applicable.
